在系列NiMo/Al2 O3 催化剂上考察了环戊酮转化为环戊硫醇的反应。根据反应结果推断 ,该硫醇化反应分两步进行 ,第一步为环戊酮和H2 S生成环戊硫酮 ,第二步为环戊硫酮加氢生成环戊硫醇。在部分所用催化剂上发现了环戊硫酮中间产物。Ni和Mo对反应具有协同作用 ,Ni的加入明显加速了第二步反应的进行 ,使反应活性和选择性大大提高
The reaction of cyclopentanone to cyclopentanethiol was investigated on a series of NiMo / Al 2 O 3 catalysts. According to the reaction results, the thiolation reaction is carried out in two steps. In the first step, cyclopentanone is formed from cyclopentanone and H2S, and cyclopentanthione is hydrogenated to cyclopentanethiol. The cyclopentanthione intermediate was found on some of the catalysts used. Ni and Mo have a synergistic effect on the reaction. The addition of Ni accelerates the reaction of the second step obviously, greatly improving the reactivity and selectivity
